dmildram> Surprised this seems a relatively NEW BUG
as opposed to an OLD BUG/vulnerability NEWly discovered.
Reading just a bit of the link Tim sent, where it says under Affected kernels,
it seems feasable that all versions from atleast (including) v5.14.21 to
(including) v6.6.14 are exploitable, depending on the kconfig values
(details below). This means that at the time of writing, the stable
branches linux-5.15.y, linux-6.1.y, and linux-6.6.y are affected by this exploit, and perhaps linux-6.7.1
doug/dmildram> I feel safe on this! unless I'm mistaken
with my aging 5.4.0 kernel on linux mint 20.
Thanks for your looking out for us in general in wlug ! -doug
